Subject: [PATCH 02/14] dt-bindings: misc: Document reg for aspeed, p2a-ctrl nodes
Date: Tue,  3 Dec 2019 22:34:03 +1030
Message-ID: <17ccbf7c6f9f7b81543eabee06d81e137c8759c6.1575369656.git-series.andrew@aj.id.au> (raw)
In-Reply-To: <cover.08e3a6c95159f017b753d0f240086d1a7923758b.1575369656.git-series.andrew@aj.id.au>

The P2A controller node sits under a syscon device, and can assume
offsets from the base of the syscon based on the compatible. However,
for devicetree correctness allow a reg property to be specified, which
an associated driver may choose to use to discover associated resources.
